I mentioned title as ifb worst brand because 2 weeks ago bought microwave oven and started to use cook n lid attached products of oven. When we started to cook the bowl which given by ifb started to melt within 3 minutes we got strange smell from oven. Money, ingredients we used for cooking and our time got waste. So be safe and don't use ifb products. We are in kitchen if it bursted out think of our lives. Thanks to almighty.
